问题描述

在对

In its answer to this question, hkaiser said he would write an example of a token type which carries code position information. I really cannot find anything about this.

有人能指出我一个这样的例子吗?

Can anyone point me to such an example ?

推荐答案

他可能是指position_token，尽管文档很少，但实际上确实已发布. 此SO问题具有很好地覆盖了它的用法.

He was probably referring to position_token, which did in fact get released, although there's little documentation. This SO question has good coverage of its usage.
